Article Abstract
We show that the wetting growth of Au on Se seed nanoparticles can be continuously tuned through manipulating the growth kinetics - the reduction rate of HAuCl and the inhibiting effect of DPI-SH ligand. As a result, a series of Se-Au hybrids and anisotropic Au semi-shell structures with different sizes were successfully obtained. With the structural variations, the absorptions of Se-Au hybrids and LSPRs of the Au semi-shells can be continuously tuned within the Visible-NIR spectral range. Our work provides convenient while efficient means for tailoring the Au-based heterostructures and the anisotropic Au nanostructures.

Lipid-based formulations have been successfully applied to improve the aqueous solubility of active pharmaceutical ingredients (APIs), however, with the bottleneck of limited wettability of the system. In this study, a lipid-based system was developed using polyglycerol ester of fatty acids (PGFA) as the main component and hexaglycerol (PG6) as a wetting agent. Felodipine, a BCS class II compound was selected as a model API.

Crystal phase control of III-V semiconductor nanowires grown by the vapor liquid solid mechanism has emerged as a new frontier in nanomaterials in the 2010s. Of particular interest is the ability to grow the metastable wurtzite crystal, which is commercially unavailable in semiconductors such as GaAs and SiGe. The successful growth of wurtzite GaAs nanowires has been demonstrated by precise control of the wetting contact angle of the catalyst particle.

Solid-state lithium metal batteries (SSLMBs) are promising for realizing higher energy density. However, the poor interfacial Li transport kinetics and Li dendrite growth inhibit SSLMBs, leading to sluggish interfacial ion diffusion and depressive lifespan, which is attributed to high barriers blocked by anions or interface space in solid-state electrolytes. Herein, a flexible solid-state polymer skeleton employed with ionic liquid and metal-organic frameworks (PIM) electrolyte is proposed to strengthen interfacial Li ion exchange by improving the Li sieving effect and interfacial wettability.

The Tibetan Plateau (TP), one of the most climate-sensitive regions in the world, has experienced significant warming and wetting in recent decades, which is widely recognized has promoted vegetation greening. However, a paradoxical phenomenon has been observed: during the growing seasons, vegetation greenness negatively correlates with precipitation across large areas of the TP. The underlying causes of this counterintuitive relationship remain unclear.

To mitigate the adverse ecological impacts of inorganic solidified materials on modified red clay and address the issues of low bearing capacity and extensive cracking under hydraulic erosion, this study investigates the use of low-environmental-impact materials to improve the mechanical fracturing of red clay. In this context, this study focuses on modifying red clay using an environmentally friendly biopolymer, xanthan gum (XG). Through a series of laboratory mechanical and microstructural tests, the effects of XG on the mechanical fracturing, California Bearing Ratio (CBR), and microstructural characteristics of red clay are examined.
